Abstract

Briefly, an extended use infusion set is provided that substantially extends the therapeutic life of an infusion set, thereby increasing patient comfort, decreasing costs, and providing for increased efficacy for infused medicines and therapeutics. Generally, the extended use infusion set uses an insertion mechanism to position a cannula or needle at an initial depth and location for subcutaneous infusion of medication. At a later time, when the therapeutic effect of the medication has decreased below a threshold, the patient uses a reset mechanism to reposition the needle or cannula to a new depth and location. In this way, the therapeutic effect of the medication is reestablished, enabling the infusion set to be used effectively for a longer period of time. The infusion set also contemplates setting and resetting a biosensor.
